ABSTRACT

The mineralogical and geochemical effects of weathering on shales
at the Panglo Deposit, Eastern Goldfields, WA

Scott, K.M. and Dotter, L.E.

Examination of phyllosilicates, oxide phases, alunite and, where
present, sulphides and carbonates in 10 samples of fresh and weathered
shale from the Panglo area has helped elucidate how elements are
retained during weathering. Chalcophile elements are strongly retained
by Fe oxides and Sr and Ba (plus As and Cu) are retained by alunite.
Micas, which are essentially unaffected by weathering, appear to
have low Na and Fe contents in mineralized profiles and higher contents
elsewhere.
